A method for producing a case-hardened martensitic stainless steel article includes: providing an article comprised, at least in part, of a martensitic stainless steel, carburizing the article within a temperature range of 1625&#xb0; F.-1680&#xb0; F. (885&#xb0; C.-916&#xb0; C.), and then carbo-nitriding the article within a temperature range of 1575&#xb0; F.-1625&#xb0; F. (857&#xb0; C.-885&#xb0; C.). An article, such as a bearing ring, comprising such a case-hardened martensitic stainless steel is also disclosed.

Carbo-nitriding process for martensitic stainless steel and stainless steel article having improved corrosion resistance

Embodiments of a coated substrate (for example, a coated race land region of a roller bearing element) comprise a metallic substrate, a ceramic underlayer comprising a nitride, a carbide, a carbonitride, a boride, or combinations thereof disposed over the metallic substrate, and a mixed layer comprising titanium nitride and silver disposed over the ceramic underlayer; and an overlayer disposed over the mixed layer.

Wear resistant coatings for race land regions of bearing materials

The present invention provides a method for applying a tribological coating to a carbon composite substrate. The method includes providing the carbon composite substrate, depositing a layer of carbon on the substrate, applying a layer of aluminum on the layer of carbon, annealing the substrate at a temperature greater than a melting temperature of aluminum, and applying a layer of silver. A layer of mixed aluminum and silver may be substituted for the layer of silver.
